BALLOON SIZING OF VALVE ANNULUS FOR PERCUTANEOUS VALVES
First Claim
Patent Images
1. A method to size a valve annulus, the method comprising the steps of:
- introducing at least part of a sizing device into a luminal organ at a valve annulus, the sizing device having a detector and a pressure transducer within a balloon positioned at or near a distal end of the detection device;
inflating the balloon until a threshold pressure is detected by the pressure transducer within the balloon;
obtaining a first valve annulus measurement using the detector; and
withdrawing the sizing device from the luminal organ.

Abstract
Balloon sizing of valve annulus for percutaneous valves. In at least one embodiment of a device to size a valve annulus of the present disclosure, the device comprises an elongated body extending from a proximal end to a distal end and having a lumen therethrough, a balloon positioned along the elongated body at or near the distal end, a detector and a pressure transducer positioned along the elongated body within the balloon, and a suction/infusion port defined within the elongated body within the balloon.

23. A system to size a valve annulus, the system comprising:
-
a device, comprising; an elongated body extending from a proximal end to a distal end and having a lumen therethrough; a balloon positioned along the elongated body at or near the distal end; a detector and a pressure transducer positioned along the elongated body within the balloon; and a suction/infusion port defined within the elongated body within the balloon; a current source coupled to the detector and the pressure transducer; and a data acquisition and processing system capable of receiving conductance data from the detector and calculating a balloon cross-sectional area based upon a detected conductance of a fluid within the balloon from the detector, a known conductivity of the fluid, and a known distance between two detection electrodes of the detector.
